| 摘要 |
The invention relates to a liquid ring compressor and/or pump, comprising a rotating compressor casing ( 1 ), a shaft journal ( 10 ) eccentrically located relative to the compressor casing's axis of rotation, with a surrounding bearing ( 15 ). One or more compressor wheels ( 14 ) with at least one vane are disposed in the compressor casing with the inside of the compressor wheel ( 14 ) in abutment against and rotating around the bearing ( 15 ) and inlet and outlet ports for the fluid that has to be compressed. When the compressor casing is rotated, a liquid ring ( 20 ) is created against the inner wall of the rotating compressor casing ( 1 ), which liquid ring ( 20 ) together with the compressor wheel ( 14 ) forms compression chambers. The liquid ring compressor further comprises at least one magnetic element mounted in the compressor casing ( 1 ) adjacent to the compressor wheel ( 14 ), where when the compressor casing ( 1 ) is rotated, the magnetic element makes the free-running compressor wheel ( 14 ) rotate at the same rotational speed as the compressor casing ( 1 ).
